A simple, mild elimination of hydrogen halide from primary alkyl bromides and iodides
Abstract
Addition of a solution of a primary alkyl bromide or iodide and 1,8-diazabicyclo[5.4.0]undec-7-ene in tetrahydrofuran (THF) to a solution prepared from dichlorobis(triphenylphosphine)nickel, triphenylphosphine, and n-butyl-lithium in THF results in an elimination at room temperature to give, in most cases, the terminal alkene.
